Low-intensity Chemotherapy Combined With Targeted-Immunotherapy for Newly Diagnosed Philadelphia Chromosome-Positive Acute Lymphoblastic Leukemia: A Prospective Clinical Cohort Study

Study Summary

This is a prospective, open-label, randomized controlled trial to evaluate the efficacy of low-intensity chemotherapy combined with venetoclax and blinatumomab in newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL). Patients will be randomized to receive or not receive venetoclax during the first three cycles of induction and consolidation therapy. All patients receive olverembatinib (a third-generation TKI) continuously and may receive up to 4 cycles of blinatumomab starting from the fourth cycle. The primary endpoint is the rate of BCR::ABL1 ≤0.01% at 90 days and event-free survival (EFS). Secondary endpoints include overall survival (OS), relapse-free survival (RFS), molecular relapse rate, MRD negativity rate by NGS, and cardiovascular events.
